The food you order online was not stolen from the server/bartender without their permission or compensation. Even if the analogy holds, this is whataboutism, and in the U.S. at least tipping is a fucked system too.
It's about applying your outrage evenly. Why put artists over a servers? Why do you drive when not using horses means many blacksmiths positions disappear. Technology that is accepted by society changes society. Artists will continue to evolve and create messages about those changes. No need to worry about their plight. Worry about translators or other industries that can't easily provide the same value. Artists are the one group who will survive and thrive.
This is how art works and has always worked. Artist should be using the same AI tools that the general public use but create things that the general public cannot. That’s what artists have always done.
Running a restaurant is a trillion other things. Ordering the right amount of ingredients. Hiring, training, and keeping staff. Cleaning the bathrooms. Replacing stolen silverware.
You're not paying for the secret recipe. There isn't one. You're paying for the insane amount of work that goes into putting cooked food on a plate.
Images are much more about the specific process that went into creation. The intellectual part that can be taken is a much higher fraction of the product.
Any attempt to compare the A.I. stuff to some analogous scenario is deeply flawed if it does not include 1) that A.I. instances are not humans, but computers run by companies, and 2) the incredible scale at which it can operate.
The actual actions taking place are secondary at best, and the situation cannot be judged on that alone. It must be debated in the context of the actions being undertaken by machines, owned by companies, motivated by profit/market share/growth/whatever, with little communication or collaboration with the humans who created the works, and that they can now generate outputs based on those works at a scale, frequency, level of precision several orders of magnitude higher than a human can ever compete with. It cannot be compared to any sort of person-to-person scenario. The enormous scale this operates at, by actors that are not human, is the core of the situation.
